Quantum entanglement
News and views Nature 7206 p831, "The Speed of Instantly" by Terence G. Rudolph dep. physics Imperial College.
If you grasp only one brain twister this year this may be the one. Salart et al conduct an experiment testing the speed or delay if any between entangled photon pairs, 18 km apart in Satigny and Jussy, Switzerland. The experiment implies a near infinite speed of quantum information between one paired entangled particle and the other. Furthermore, there appears no loss of strength with distance. The implications for communication and computing seem endless. The application of entanglement with quantum computing suggests a whole new paradigm for information, communication and computing.
